  • Spring reset mechanism
    Patent number: 4116280
    Abstract: A safety trip mechanism for a ground working tool utilizes a roller pin engageable with a notched and spring biased latch to resist collapse of a toggle linkage and rotation of the tool supporting standard as obstacles are encountered by the tool. The roller pin is rigidly connected to one toggle link and spaced from the frame which supports the standard to reduce the breakout force acting on the pin. Flattening of the roller pin surface and wear between the pin and its latch are accordingly reduced to improve reliability of the trip mechanism and decrease maintenance.
